well i am adding this information for all those guys whoz cars are registered from ISB ETO, first of all the provisional stamp and paying token tax both are different things, i discuss them one by one and finally i discuss how to get the red book;
1) Provisional stamp(the guy to catch in ETO isb is Sultan, he sits on top floor): well one apply for registration they send ur documents for verification to the company from which u purchase the vehicle say Toyota, honda or suzuki. This time of verification of documents varies from few months to year, u have to keep in touch with ETO office once ur documents are verified from ur company, (they actually send ur submitted vehicle documents for verfication), they will simple cancel the Provisional stamp and replace it will original copy stamp.
2) Token tax: well when u do ur registration they put a date in ur documents saying tax to be recovered w.e.from... so after that its due to pay the tax, if u see on ur copy there will be stamp which indicates that before that date u have to pay the tax, procedure is simple, goto the ur postoffice, means the address which u mention in ur book (in isb u can only pay token tax in ur relevant PO box, wese tu is ka bhi aik cheat hai anyways), u will goto ur Post office, they will do the entry do take copies of the papers u have, it will save time, simple, now let say u don't know about that stamp, then when u go to Post office they guy will say the date is over , then u have to goto ET office and u have to restamp it, its for free, no need to pay any peny to anyone, that the corner window on front, tell they guy to stamp it for token tax.
3) how to get the red book: well there are two ways
i) For vehicle registered before 2011 the procedure was different, u were supposed to apply for red book or computerized book, once u get ur provisional stamp removed, u just have to pay i think 350 Rs and after one week u would be provided the red book, in that case they gave u a slip and they keep ur original documents slip (that can also be done in one day azwell)
ii) For vehicle registered after 2011 the procedure is very simple, at time of registration they charge u that 350 rs of red book and 50 Rs for courier and they send the red book to ur home after one month of ur registration, but this red book will be having provisional stamp, u pay token tax the same way, when ur documentss are verfied they will put original stamp on it
